Title: Improvements in vehicle lamps
IPC: F21V7/04
Filed: 1931-05-22
Abstract: 376,431. Vehicle lamps. RIDE, T. A. F., 892, Chester Road, Erdington, Birmingham. May 22, 1931, No. 15127. [Classes 75 (ii), 75 (iii), and 75 (iv).] Reflectors ; lantern fronts ; supporting.-A vehicle lamp has a reflector comprising a main reflector 12 which projects a horizontal beam from the main source of light 8, and a subsidiary reflector which is integral with the main reflector and projects light from the subsidiary light source 11 in a forward and downward direction, the subsidiary reflector comprising a part spherical or parabolic portion 13 and a part cylindrical portion 14. The casing is of cast aluminium or other metal, and has the reflecting surfaces formed on its interior surface by polishing or plating. Alternatively, the casing may be pressed or spun. The main reflector may be substantially parabolic. Screw-threaded parts 6, 9 of clips 7, 10, into which are slid the holders of the bulbs 8, 11, are threaded into bosses formed on the reflector. The front cover has an annular frame 15 with two flanges 16, 38, the glass 17 being held in position by a washer 18 and a spring ring 37. Bolts passing through integral lugs on the casing and cover secure it in position. An attachment portion 3 formed on the casing is mounted in a correspondingly shaped seating on the vehicle, and is recessed on its underside at 23, an attached bolt 24 being pivoted therein. In another form, the reflecting surfaces are provided on a separate member of silvered glass or polished or plated metal, mounted within the casing. The upper part 34 of the lamp front may be coloured yellow, amber, or otherwise, by applying colouring material to the interior surface of the glass or by securing a coloured transparent member to the surface of the glass.

[Also in Division F2] A method of making a collapsible tubular member having predictable collapsing characteristics for use for example in the steering shaft assembly of motor vehicles comprises the steps of providing a tubular blank 10 with an intermediate wall section deformed symmetrically about the longitudinal axis of the blank and having axially spaced end sections 26, 28 (Fig. 2) and applying a predetermined axial force to produce relative axial movement of the end sections towards one another so that the intermediate wall section collapses into a predetermined pattern (Fig. 4) and applying a tensile axial force to the end sections to partially restore the collapsed intermediate wall section to its original configuration (Fig. 6) to complete the structural member. In order to control the force necessary to initiate collapse of the member in use circumferentially spaced notches are cut in the outer radial portions of the corrugations.

Title: Process for the manufacture of unsaturated ketones of the cyclopentano-polyhydrophenanthrene series
IPC: C07J75/00
Filed: 1937-06-01
Abstract: 500,186. Sex hormones. SCHERING KAHLBAUM AKT.-GES. June 1, 1937, No. 15255. Convention date, June 2, 1936. Samples furnished. [Class 2 (iii)] Unsaturated ketones of the cyclopentanopolyhydrophenanthrene series are prepared by treating the corresponding secondary alcohols in the form of their metal alcoholates or in the presence of other metal alcoholates with the exception of a tertiary alcoholate of aluminium or a tertiary alcoholate of magnesium chloride with an excess of an aldehyde or a ketone. In the cases where other metal alcoholates are used, the preferred compounds are magnesium or aluminium alcoholates. The larger the excess of the aldehyde or ketone which is employed the more complete is the oxidation. The process is stated to yield a very pure product, so that simple recrystallization is all that is necessary to give complete purity. Chemical purification methods, such as by means of semicarbazide may, however, also be employed. In examples : (1) a cyclohexanone solution of cholesterol is treated with aluminium isopropylate for four hours at 100 C. and then steam distilled. Interaction with semicarbazide gives the semicarbazone of cholestenone; (2) a xylene solution of cholesterol is treated with aluminium isopropylate to form aluminium cholesterylate. This is then oxidized to cholestenone with cyclohexanone; (3) cholesterol is converted into cholestenone by means of magnesium chlorethylate in a manner similar to the process of example (1); (4) a cyclohexanone solution of pregnenol-(3)-one-(20) is treated with aluminium isopropylate to give the corpus luteum hormone; (5) a oyclohexanone solution of dehydroandrosterone is treated with aluminium isopropylate to give androstendione: (6) a cyclohexanone solution of androstendiol-monobenzoate-(17) is treated with aluminium isopropylate to give testosterone benzoate. Small amounts of starting material are removed by reaction with phthalic anhydride. Samples have been furnished under Sect. 2 (5) of: (1) stigmastadienone prepared by the treatment of stigmasterol in acetone solution with aluminium isopropylate; (2) corpus luteum hormone prepared by the treatment of pregnenol-(3)-one-(20) in xylene solution with an acetone solution of aluminium isopropylate ; (3) testosterone benzoate prepared by the treatment of androstendiol-monobenzoate-(17) in cyclohexanone solution with aluminium isopropylate. Unchanged starting material is removed with phthalic anhydride.

Title: Improvements in or relating to pile fabrics
IPC: A41H41/00
Filed: 1942-11-10
Abstract: A pile fabric of which the pile comprises flat filaments of a cellulose derivative is treated with a boiling aqueous medium so as to crinkle the pile filaments, and before or after this treatment, the backing is rendered wind- or water-proof by impregnating it with a synthetic hydrophobe coating material, e.g. a synthetic resin, a synthetic rubber, or a cellulose derivative. An alkyd resin, a derivative of polyvinyl alcohol or of polyacrylic or polymethacrylic acid, an interpolymer of two or more dienes or of a diene and acrylo-nitrile or styrene or isobutylene may be used.  Suitable dienes are 1.3-butadiene, isoprene and chloroprene.  When a cellulose derivative proofing material is used it may be an ester such as acetate, butyrate, or aceto-stearate, or an ether such as ethyl, hexyl, or benzyl cellulose.  The proofing material may be applied as a paste, emulsion, or thickened solution over the back of the fabric by means of a roller or spreading knife.  The solvent or dispersion medium is removed and heat may be applied to increase water-resistance and to reduce tackiness.  Synthetic resins may be applied in partially condensed or polymerised, or unpolymerised state and condensation or polymerisation is completed on the fabric. Plasticisers, pigments, fillers and other substances may be incorporated in the proofing liquids.  The treated fabrics may have the appearance of lamb's wool.
